Which of the following is NOT true of President Hoover?

President Hoover was elected and inaugurated just before the stock market crash of 1929 and the beginning of the Great Depression.

President Hoover, just like President Coolidge and Harding before him, advocated for low taxes, high tariffs and less government spending and regulations.

President Hoover immediately upon being elected ended the policy of buying stock on margin and shut down all banks in the US to stop "bank-runs" from occurring.
